Second lens recommendation for GX1?

Hi all.  It's been a while since I have been here.  Originally back in 2001 when I had my minolta!

With the Panasonic GX1 on sale, my buddy and I both picked one up with the kit 14-45 lens.  The 14-45 lens is less than appealing, but it serves it's function for now.  I was hoping indoor shots would be better, but the lens is too slow....so I am looking for a second lens for now.  Mainly low light, people/objects/animals.  I have narrowed it to the following lenses.

PANASONIC LUMIX G 14mm F2.5 $180

PANASONIC LUMIX G 20mm F1.7$350

Olympus 25mm f/2.8 Pancake Lens $250

All three seem to get good reviews.  I am afraid the 25mm won't be wide enough for indoor shots.  I hear the 20mm is really slow to focus, but great everywhere else.  Most people seem happy with the 14mm that have it.

Any opinions?  The 14mm seems like a good deal at almost half the cost of the 20 mm.  But, I have a feeling the 20mm would perform better indoors without a tripod. The 25 looks like a good lens and priced well.  Just afraid it will under-perform compared to the others.  I'd like to eventually end with a 14mm, 20/25mm, 45mm, and some sort of zoom 45-150/200. Money is an issue though so I am looking at probably 6 months before the next lens.  Thoughts welcomed!
